Calculation of Bandwidth of Multimode Step-Index Polymer Photonic Crystal Fibers
(MDPI, 2021-12-01)By solving the time-dependent power flow equation, we present a novel approach for evaluating the bandwidth in a multimode step-index polymer photonic crystal fiber (SI PPCF) with a solid core. The bandwidth of such fiber ... -
Calculation of the bandwidth of W-type photonic crystal fibers by time-dependent power flow equation
(Elsevier, 2018-06-30)A multimode photonic crystal fiber with a solid-core takes the characteristic W-shaped index profile upon forming an inner cladding layer with its own value of the effective refractive index corresponding to the distinct ... -
Calculation of the mode coupling coefficient in step-index plastic optical fibers based on the far field measurements
(Frontiers, 2022-05-25)Using the power flow equation (PFE), this article investigates mode coupling in step-index (SI) multimode (MM) polymer optical fiber (POF). This equation’s coupling coefficient was initially fine-tuned so that it could ... -
Caristi, Nadler and H + -Type Contractive Mappings and Their Fixed Points in θ-Metric Spaces
(MDPI (Basel, Switzerland), 2019-04-07)A new proper generalization of metric called as θ -metric is introduced by Khojasteh et al. (Mathematical Problems in Engineering (2013) Article ID 504609). In this paper, first we prove the Caristi type fixed point theorem ... -
Cartesian Dualism and Plotinus’ Philosophy of Mind
(MGIMO University Press., 2019)In this paper my intention is to tackle a few issues concerning some interpretations of Plotinus’ “philosophy of mind”. Firstly, I will address the validity of the idea that Plotinus was “the first Cartesian”, advocated ... -
Case study-Review of sensory integration treatment of child diagnosed within sensory processing disorders and developmental dysphasia
(Acupuncture & Electro-Therapeutics Research International Journal of Integrated Medicine, 2018-09-21)Introduction: The importance of early intervention and speech – language therapy in working with children with developmental dysphasia need not be specially emphasized because it has been confirmed many times by numerous ... -
Causality between stopped filtrations and some applications
(2021-11-21)In this paper we consider the concept of statistical causality in continuous time between filtrations associated with stopping times, which is based on Granger’s definition of causality. Especially, we consider a ... -
